Biotin (vitamin B8) is a water soluble vitamin also known as Vitamin H.
Biotin is a coenzyme involved in the metabolism of fatty acids, carbohydrates and amino acids and synthesis of vitamins B9 and B12
We find the biotin, among others, in whole grains, liver, eggs and milk.
It is often used in experimental biochemistry because of its affinity for the extremely important and streptavidin for avidin.
Warning: biotin is sometimes mistakenly called vitamin B7.
Biotin is made between a core of 2-imidazolidinone, fused to a core Thiolane, which is attached a propionic acid group.
